Gyroscope

class in UnityEngine

切换到手册描述

访问陀螺仪的接口。

可以使用该类访问陀螺仪。下面的示例脚本演示了如何使用 Gyroscope 类查看设备在空间中的方向。用于数据填充的基础传感器：Android：重力、线性加速度、旋转矢量。更多信息。iOS：陀螺仪、设备运动。更多信息。

// Create a cube with camera vector names on the faces. // Allow the device to show named faces as it is oriented.using UnityEngine;public class ExampleScript : MonoBehaviour { // Faces for 6 sides of the cube private GameObject[] quads = new GameObject[6]; // Textures for each quad, should be +X, +Y etc // with appropriate colors, red, green, blue, etc public Texture[] labels; void Start() { // make camera solid colour and based at the origin GetComponent().backgroundColor = new Color(49.0f / 255.0f, 77.0f / 255.0f, 121.0f / 255.0f); GetComponent().transform.position = new Vector3(0, 0, 0); GetComponent().clearFlags = CameraClearFlags.SolidColor; // create the six quads forming the sides of a cube GameObject quad = GameObject.CreatePrimitive(PrimitiveType.Quad); quads[0] = createQuad(quad, new Vector3(1, 0, 0), new Vector3(0, 90, 0), "plus x", new Color(0.90f, 0.10f, 0.10f, 1), labels[0]); quads[1] = createQuad(quad, new Vector3(0, 1, 0), new Vector3(-90, 0, 0), "plus y", new Color(0.10f, 0.90f, 0.10f, 1), labels[1]); quads[2] = createQuad(quad, new Vector3(0, 0, 1), new Vector3(0, 0, 0), "plus z", new Color(0.10f, 0.10f, 0.90f, 1), labels[2]); quads[3] = createQuad(quad, new Vector3(-1, 0, 0), new Vector3(0, -90, 0), "neg x", new Color(0.90f, 0.50f, 0.50f, 1), labels[3]); quads[4] = createQuad(quad, new Vector3(0, -1, 0), new Vector3(90, 0, 0), "neg y", new Color(0.50f, 0.90f, 0.50f, 1), labels[4]); quads[5] = createQuad(quad, new Vector3(0, 0, -1), new Vector3(0, 180, 0), "neg z", new Color(0.50f, 0.50f, 0.90f, 1), labels[5]); GameObject.Destroy(quad); } // make a quad for one side of the cube GameObject createQuad(GameObject quad, Vector3 pos, Vector3 rot, string name, Color col, Texture t) { Quaternion quat = Quaternion.Euler(rot); GameObject GO = Instantiate(quad, pos, quat); GO.name = name; GO.GetComponent().material.color = col; GO.GetComponent().material.mainTexture = t; GO.transform.localScale += new Vector3(0.25f, 0.25f, 0.25f); return GO; } protected void Update() { GyroModifyCamera(); } protected void OnGUI() { GUI.skin.label.fontSize = Screen.width / 40; GUILayout.Label("Orientation: " + Screen.orientation); GUILayout.Label("input.gyro.attitude: " + Input.gyro.attitude); GUILayout.Label("iphone width/font: " + Screen.width + " : " + GUI.skin.label.fontSize); } /********************************************/ // The Gyroscope is right-handed. Unity is left handed. // Make the necessary change to the camera. void GyroModifyCamera() { transform.rotation = GyroToUnity(Input.gyro.attitude); } private static Quaternion GyroToUnity(Quaternion q) { return new Quaternion(q.x, q.y, -q.z, -q.w); } }

\ 显示 +Z、+Y 和 -X 的 iOS 屏幕截图。

变量 attitude返回设备的姿态（即在空间中的方向）。 enabled设置或检索该陀螺仪的启用状态。 gravity返回以设备参考系表示的重力加速度矢量。 rotationRate返回设备陀螺仪测量的旋转速率。 rotationRateUnbiased返回设备陀螺仪测量的无偏差旋转速率。 updateInterval设置或检索陀螺仪间隔时间（以秒为单位）。 userAcceleration返回用户给予设备的加速度。
